My auntie is a driving instructor, and I'm pretty sure some of the pupils are worse than the instructors. People come out in their pyjamas, don't pay, don't wash, cancel 10 minutes before the lesson, don't cancel and just don't turn up. The worst is when people buy 10 lessons then spread them out over 10 months and complain when they don't pass.
So, don't blame the instructor all the time. Although I'm sure there are ****ty ones too. It's strange hearing it from the other side.
